SP.A.1/S3 – Magnetic rectangular prox. sensor

Why Choose the Carlo Gavazzi SP.A.1/S3 Magnetic Proximity Sensor?

The Carlo Gavazzi SP.A.1/S3 is a robust rectangular magnetic proximity sensor designed for reliable non-contact position detection and switching in industrial machinery and automation systems. As part of the Carlo Gavazzi SP.A.1 magnetic sensor series, it combines two normally closed relay contacts in a compact housing, providing separate signalling and high-power switching functions.

The SP.A.1/S3 provides a 5 VA low-power signalling contact together with a 100 VA high-power contact for controlling more demanding loads. Its magnetic operating principle enables dependable switching without direct mechanical actuation, helping reduce wear and support a long operational life in industrial applications.

Designed for a 24 V DC supply, the SP.A.1/S3 features an IP67-rated ABS Class V0 housing measuring 90 × 20 × 16 mm. The S3 version uses a thin plate fixed to the sensor case for the ground connection, while its PVC cable with connector supports straightforward integration into machinery and control systems.

Reliable Magnetic Position Sensing for Industrial Machinery

Magnetic proximity sensors detect the position or movement of a suitable magnetic actuator without requiring conventional mechanical contact. This sensing method provides reliable switching while minimising mechanical wear, making it well suited to machine guarding, position monitoring and industrial automation applications.

The Carlo Gavazzi SP.A.1 series is particularly useful where separate signalling and load-switching functions are required. The SP.A.1/S3 combines a low-power contact for signalling with a higher-power contact for switching heavier loads, while its distinctive ground connection uses a thin plate fixed directly to the sensor case.

Typical Applications

• Industrial machine position detection.
• Machine guards, doors and access panels.
• Automated production and assembly equipment.
• Conveyors and material handling systems.
• Industrial control and signalling circuits.
• OEM machinery and automation systems.
